Dynamic parameter, water-use, stream and lake flow routing, and two summary output modules and updates to surface-depression storage simulation and initial conditions specification options for the precipitation-runoff modeling system (PRMS)

This data release documents seven enhancements to the U.S. Geological Survey (USGS) Precipitation-Runoff Modeling System (PRMS) hydrologic simulation code: two new time-series input options (dynamic parameter module and water-use module), two new output options (Hydrologic Response Unit (HRU) summary output module and basin variables summary output module), and three updates of existing capabilities (stream and lake flow routing module, surface-depression storage and flow simulation, and the initial-conditions specification). This report relies heavily upon U.S. Geological Survey Techniques and Methods, book 6, chapter B7 (http://dx.doi.org/10.3133/tm6b7) that documents PRMS version IV (PRMS-IV). Example applications of the enhancements are included in this data release. This child page contains the output files for the seven scenario simulations using the example PRMS model. File baseline_statvar.csv is for the baseline simulation. File dyn_params_statvar.csv is for the dynamic parameters simulation. File init_vars_save_statvar.csv is for the initial conditions file creation simulation. File init_vars_use_statvar.csv is for the use of initial conditions file simulation. File muskingum_lake_flow_replacement_statvar.csv is for the simulation using the flow replacement option in the muskingum_lake module. File muskingum_lake_flow_through_statvar.csv is for the simulation using the flow through option in the muskingum_lake module. File water_use_statvar.csv is for the water use module simulation.

本数据集发布内容涵盖美国地质调查局（U.S. Geological Survey, USGS）降水-径流模拟系统（Precipitation-Runoff Modeling System, PRMS）水文模拟代码的七项改进：两项新增时序输入功能模块（动态参数模块与用水模块）、两项新增输出功能模块（水文响应单元（Hydrologic Response Unit, HRU）汇总输出模块与流域变量汇总输出模块），以及三项现有功能的更新（河道与湖泊汇流演算模块、地表洼地蓄存与径流模拟功能，以及初始条件设定功能）。

本报告主要参考了记载PRMS第4版（PRMS-IV）的《美国地质调查局技术与方法》丛书第6卷B7章（http://dx.doi.org/10.3133/tm6b7）。

本数据集发布内容中包含了各项改进的示例应用。
