Operational Decision Support Tool for Rancho California Water District

Rancho California Water District

Introduction

Welcome to the Demo Operational Decision Support Tool (Tool) created for Rancho California Water District.

This Tool is coupled with the Murrieta-Temecula Basin groundwater model to simulate projected groundwater conditions beneath the District within a user-defined simulation period and hydrologic outlook. Within the user-interface, users can define:

Length of simulation period

Precipitation values

Imported water volumes to recharge facilities

Groundwater pumping rates by well or subunit

Results from this Tool can guide District operational decisions to efficiently meet demands while limiting the impact on the Basin's groundwater supply. Simulated groundwater conditions can be reviewed via:

Well hydrographs

Time-series water level contour maps

Water level change summary tables

Groundwater storage plots

Objectives

The District's mission is to deliver reliable, high-quality water to its customers and communities in a sustainable manner. This Tool is intended to help the District accomplish that mission by:

Empowering the District and its stakeholders to be more proactive about managing water resources

Enhancing District / stakeholder understanding of basin hydrogeological dynamics

Optimizing water resources conjunctive use strategies for operational efficiency and long-term sustainability

Automating figure and summary table generation for annual water audit reporting

Select the number of simulation years and click the "Generate Hydrology" button to automatically assign precipitation values for each year.

Number of simulation years:

Hydrologic Inputs

Selection of "Water Year Type" will determine how much precipitation is assigned for each year based on historical precipitation observations from weather stations within the basin.

Recharge Operations

This section dictates how much water is imported to the Valle De Los Caballos (VDC) recharge ponds.

Enter a recharge volume (AF):

Assign Recharge Rates by Facility

Well Production Operations

This section dictates how much water is pumped from production wells within the model based on a user-assigned value. Options allow for production rates to be assigned by hydrologic subunits or specific wells. If assigned by hydrologic subunit, production rates are distributed amongst wells based on actual fiscal year (FY) 2023 (July 2022 to June 2023) production rates in each subasin.

Assign default production rates based on:

FY 2023 Rates

FY 2019-2023 5-Year Average

Double click on a "Production Rate (AF)" value to edit.

Assign Production Rates by Well

Select an option from the dropdown list to view wells within a hydrologic subunit.

Select a subunit:

Double click on a "Production Rate (AF)" value to edit.
