GroMoPo Metadata for Soan watershed MODLFOW model

Numerical modeling of an aquifer is increasingly used as a power tool for monitoring and management of groundwater. This paper focuses on conceptualizing hydrogeological condition and establishing numerical simulation model using Visual MODFLOW to simulate the continuous depletion of groundwater in the southwestern part of the Soan watershed in Pakistan. An integrated groundwater modeling and management approach was adopted to provide suitable alternatives for water management in different hydro-environments. Geospatial techniques were employed for spatial database development, integration with a remote sensing (RS), and numerical groundwater flow modeling capabilities to simulate groundwater flow behavior. The calibration results indicated a reasonable agreement between the calculated and observed heads. The calibrated heads were used as initial conditions in the transientstate modeling. The modeling approach facilitated in identifying potential groundwater regime besides providing artificial recharge options for sustainable groundwater development.

含水层（aquifer）数值模拟正日益成为地下水监测与管理的有力工具。本文以巴基斯坦索安流域（Soan watershed）西南部为研究区域，通过Visual MODFLOW构建数值模拟模型以刻画该区域地下水持续枯竭过程，并完成水文地质条件（hydrogeological condition）概化。本研究采用集成化地下水模拟与管理方法，为不同水文环境下的水资源管理提供可行方案。研究借助地理空间技术完成空间数据库构建，并集成遥感（Remote Sensing，简称RS）与地下水流数值模拟能力，以模拟地下水流运动特征。校准结果显示，模拟水头与实测水头之间具有较好的一致性。校准后的水头被用作瞬态（transientstate）模拟的初始条件。该模拟方法不仅可为地下水可持续开发提供人工补给方案，还能助力识别潜在地下水动态类型。
