Introduction
Introduction Hydrology

Problem?.

  • Constructed wetland : a solution for nitrate removal

  • Design of wetland- location identification

  • Evaluation of effectiveness of constructed wetland

Depth of water?

Residence time?

Objectives

  • To determine monthly average depth of water in wetland

  • To find out the area extend of wetland (monthly)

  • Estimate residence time


Study area
Study area Hydrology

  • Middle Wabash- Little Vermillion

  • HUC 05120108


Data required
Data Required Hydrology

  • Data required for location identification

  • Data required to find out the depth

  • Ditch flow to the wetland

  • Wetland Characteristics- size, normal pool depth

  • Watershed Characteristics- area, percentage tile drained

  • Evapotranspiration from wetland


Methodology
Methodology Hydrology

  • Begin with available ditch flow data and dam characteristics

  • Model the wetland inflow and outflow (possibly HEC)

  • Obtain monthly depth of water in wetland

  • Try to estimate the ditch flow data- as a function of watershed characteristics, rainfall etc.
