Modelling the hydrologic role of glaciers within a Water Evaluation and Planning system (WEAP): a case study in the Rio Santa watershed, Peru

This case study describes the development of an integrated modelling system using the Water Evaluation and Planning (WEAP) system to analyze the hydrologic role of glaciers in the Rio Santa watershed of Peru, intended as a decision support tool for climate change adaptation.

• The authors utilized the Water Evaluation and Planning (WEAP) system to model Andean glaciers' role in watershed hydrology to create a tool for assessing water management implications resulting from future glacier retreat.
• The study focused on the Rio Santa watershed in Peru, specifically targeting four objectives: simulating monitored glacier retreat and river flows from the previous forty years, quantifying the proportion of river flow from melting glaciers, estimating historical groundwater accretion contributions, and simulating recent hydropower operations.
• The research aims to provide a decision support tool for planning water management adaptation to climate change to improve the resilience of developing Andean economies, such as Peru, against varying future climatic conditions.
