Hydrometry — Subsurface dykes and ground water dams for conservation and recharge

Scope

This document outlines the hydrometry techniques through geological and geophysical considerations for the identification of suitable sites for the construction of subsurface dykes and groundwater dams aimed at water conservation and recharge. It covers the evaluation of geological formations, including soil types, rock permeability, and aquifer characteristics, to ensure the effectiveness of subsurface structures. The standard includes methods for stratigraphic analysis to identify impermeable layers necessary for water retention, as well as hydrogeological mapping techniques to determine groundwater flow patterns and recharge zones. By providing a comprehensive framework for site selection, this standard seeks to promote sustainable water resource management and enhance groundwater recharge through scientifically informed practices.
