Water entering the system (river headflows, surface water inflows to reaches, groundwater recharge, local reservoir inflows, other local supply inflows, catchment precipitation).
Water leaving the system (consumption at demand sites, catchment evapotranspiration (ET Actual), evaporation on river reaches and reservoirs, losses in transmission and return flow links, groundwater and local reservoir overflow, losses in wastewater treatment, and outflows from the end of rivers and diversions that do not flow into other rivers or groundwater nodes).
Note: Inflows to area may not equal total outflows from area due to changes in storage in reservoirs and groundwater.
Streamflow: The streamflow at selected nodes and reaches along a river. You can plot a line for each point on the river over time (choose Year for the X Axis, or a line for each month plotted along the river (choose River Nodes and Reaches for the X Axis).
Reach Inflows and Outflows: A mass balance of all water entering and leaving each river reach. Inflows (from groundwater, other surface water inflow and the upstream node) are represented as positive amounts, outflows (to groundwater, evaporation, catchments (river flooding) and the downstream node) as negative amounts.
Streamflow Gauge Comparison: Side-by-side comparison of Modeled and Observed streamflows at the node immediately above a streamflow gauge. Calibration statistics are shown on the right underneath the legend, and also on their own tab ("Statistics"). You may select one or more of the following fourteen statistics to view (use the "Statistics" dropdown above the legend to choose): N, Missing, NSE, KGE, NRMSE, PBIAS, RSR, LogNSE, InvNSE, SqrtNSE, RMSE, MAE, r, r^2. See Calibration Statistics for more information.
Streamflow Relative to Gauge (Absolute): The absolute difference between streamflow gauge data (observed streamflow) and the simulated streamflow at the node immediately above the gauge (simulated minus observed).
Streamflow Relative to Gauge (%): The relative difference between streamflow gauge data (observed streamflow) and the simulated streamflow at the node immediately above the gauge (simulated divided by observed, where 100% means the simulated value is the same as the observation).
Stage: The depth of water at selected nodes and reaches along a river.
Velocity: The velocity of water flow at selected nodes and reaches along a river.
IHA Parameters: View Indicators of Hydrologic Alteration (IHA) Parameters for streamflow. Most indicators are only available for daily timestep models.
Environmental Flow Components (EFC): Streamflow categorized into five major, ecologically important, components: extreme low flows, low flows, high flow pulses, small floods, and large floods. EFC, RVA and HA are only available for models with a daily timestep.
Environmental Flow Components Thresholds: The thresholds that separate the five major components of flow. For single-period analyses, the EFC thresholds are computed based on the entire period; for two-period or multiple-scenario analyses, the EFC thresholds are computed based on the pre-impact period or reference scenario, and then applied to the post-impact period or alternative scenarios.
Range of Variability Approach (RVA) Boundaries: The boundaries that divide each IHA parameter into the three RVA categories (Low, Middle and High). The Range of Variability Approach (RVA) compares the natural variation in the IHA parameters from the pre-impact period to the variation in the post-impact (or reference vs. alternative scenarios) to determine the extent of the changes. Each IHA parameter is analyzed to determine the frequency with which it falls into one of three RVA categories (Low, Middle, High), as defined by the RVA Category Boundaries. The change in frequency from pre-impact to post-impact of each IHA parameter is reported as the Hydrologic Alteration (HA) for that parameter. EFC, RVA and HA results are only available for models with a daily timestep.
Hydrologic Alteration (HA): The factor that describes the change in frequency (from pre-impact to post-impact, or reference to alternative scenario) of an IHA parameter for each of the three RVA categories. EFC, RVA and HA results are only available for models with a daily timestep.
Flow from Surface Water to Groundwater (Constrained): Simulated flow (seepage) from surface water to groundwater; negative values represent flow from groundwater to surface water. If the estimated flow from surface water to groundwater exceeds available flow in the river (entered as data for "Groundwater Outflow Volume," or as calculated by the "Model GW-SW Flows" method or from a linked MODFLOW model), the estimated flow will be reduced to equal the streamflow. This report shows the flows AFTER any required reductions were made, and is only available if groundwater nodes use the "Model GW-SW Flows" method. You can also see these flows on the Groundwater Inflows and Outflows report.
Flow from Surface Water to Groundwater (Unconstrained): Simulated flow (seepage) from surface water to groundwater; negative values represent flow from groundwater to surface water. If the estimated flow from surface water to groundwater exceeds available flow in the river (entered as data for "Groundwater Outflow as Volume," or as calculated by the "Model GW-SW Flows" method or from a linked MODFLOW model), the estimated flow will be reduced to equal the streamflow. This report shows the original, unconstrained estimated flow. (Note: The Groundwater Inflows and Outflows report shows the groundwater-surface water flows AFTER any required reductions were made.)
Storage: The aquifer storage levels at the end of each month.
Inflows and Outflows: A mass balance of all water entering and leaving a specified aquifer. Inflows (from recharge, inflow from river reaches, and return flows from demand sites and wastewater treatment plants) are represented as positive amounts, outflows (withdrawals by demand sites and outflows to river reaches) as negative amounts.
Overflow: Groundwater overflow occurs when the aquifer storage is at its maximum, and there is net inflow. Any overflow is lost from the system.
Height Above River: The difference in elevation between the water table and the wetted depth of the river, based on the reference groundwater elevation equal to the wetted depth that is specified when setting up the groundwater-surface water interactions.
Outflow to River: The volume of groundwater flowing to a river through the streambed. A negative value represents inflow to groundwater from the river. (Results are only available here if you are using the "Model GW-SW Flows" method.)
MODFLOW and MODPATH: See MODFLOW Results and MODPATH Results
Storage Volume and Zones: Reservoir storage compared to the operating zones (Top of Conservation, Top of Buffer, Top of Inactive), for a single reservoir.
Storage Volume: The reservoir storage volume at the end of each month.
Storage Elevation: The elevation of the reservoir level at the end of each month.
Inflows and Outflows: All water entering and leaving a specified reservoir. Inflows (either from upstream (river reservoirs) or monthly inflow (local reservoirs) or return flows from demand sites and wastewater treatment plants) are represented as positive amounts, outflows (to downstream, evaporation, local reservoir overflow, or withdrawals by demand sites) as negative amounts. For local reservoirs, evaporation and overflow are lumped together.
Evaporation: The volume of net evaporation for each month.
Local Reservoir Overflow: The volume of water that exceeds a local reservoir's Top of Conservation threshold and overflows each month (lost from the system).
Refills: For each reservoir, a value of 0 means that the reservoir did NOT refill completely after its lowest point; a value of 1 means that it did refill. Some algorithms for determining reservoir safe yield mandate that the reservoir must refill completely after its lowest point in order to be considered a safe yield.
Observed Volume: Historical observations for reservoir storage, if entered in the reservoir observed volume data variable.
Storage Gauge Comparison: Side-by-side comparison of Modeled and Observed storage. Calibration statistics are shown on the right underneath the legend, and also on their own tab ("Statistics"). You may select one or more of the following fourteen statistics to view (use the "Statistics" dropdown below the title to choose): N, Missing, NSE, KGE, NRMSE, PBIAS, RSR, LogNSE, InvNSE, SqrtNSE, RMSE, MAE, r, r^2. See Calibration Statistics for more information.
Hydropower Generation: The power generated by reservoirs and hydropower nodes.
Hydropower Turbine Flow: Actual flow through turbines. (Any flow exceeding the maximum turbine flow will bypass the turbines.)
Hydropower Demand (Energy): The energy demand specified (as data) for each reservoir and run of river hydropower node.
Hydropower Demand (Flow): The equivalent flow required to produce the hydropower energy demand.
Hydropower Unmet Demand: How much of the hydropower energy demand that was not met.
Hydropower Coverage: The percentage of the hydropower energy demand that was met.
Hydropower Reliability: The percent of the timesteps in which a reservoir's hydropower energy demand was fully satisfied. For example, if a reservoir has unmet hydropower energy demands in 18 months out of a 10-year scenario, the reliability would be (10 * 12 - 18) / (10 * 12) = 85%.
System Hydropower Generation: The total power generated by all reservoirs and hydropower nodes which are contributing to the system hydropower demand.
System Hydropower Demand: The power generated by reservoirs and hydropower nodes.
System Hydropower Unmet Demand: The energy demand specified (as data) for the system as a whole.
Note: Reports related to hydropower demand will only be available if hydropower demand data has been entered.
Inflows and Outflows: A mass balance of all water entering and leaving a specified other supply source. Inflows are represented as positive amounts, outflows as negative amounts.
Flow: The flow into each transmission link. If there are losses in the transmission link, the flow into the transmission link will be larger than the flow out of the transmission link (to the demand site or catchment), and is the best way to report the actual abstractions made.
Inflows and Outflows: Includes amounts lost to evaporation and leakage.
Flow: The flow through each return link.
Inflows and Outflows: Includes amounts lost to evaporation and leakage.
Flow: Volume of flows from catchments to surface and groundwater. Note: if there is any irrigation use of runoff, the flow values shown when viewing results on the map will be BEFORE the irrigation amount was removed.
Runoff/Infiltration Flow Inflows and Outflows: Includes any irrigation use of runoff.
