Hydrology 

INTRODUCTION

The relationship between trees and hydrology is a pivotal aspect of ecosystem dynamics, influencing water availability, quality, and flow patterns. Trees play a crucial role in the hydrological cycle by absorbing and transporting water through their roots and leaves, a process known as evapotranspiration. This not only regulates local temperature but also significantly affects precipitation patterns.

Urbanization and land-use changes, however, can disrupt this delicate balance, leading to altered hydrological patterns, increased runoff, and decreased groundwater recharge. Understanding and preserving the intricate interplay between trees and hydrology in urban environments is vital for sustainable water management, particularly in the face of global environmental challenges. Viewing trees as urban infrastructure recognizes their crucial role in addressing environmental challenges. Incorporating green infrastructure, including trees, in urban planning offers a more sustainable solution to mitigate water management issues. By integrating green spaces and preserving urban tree canopies, cities can enhance resilience against flooding, reduce runoff, and foster overall ecological balance, contributing to a healthier and more sustainable urban environment

Urban trees play a crucial role in stormwater management in urban areas. They help reduce stormwater runoff by intercepting rainfall, increasing evapotranspiration, and promoting infiltration into the soil. 

OPTIMAL URBAN FOREST LOCATIONS FOR HYDROLOGY 

We considered four key factors at the intersection of our hydrology analysis and urban forests: digital elevation model (DEM), slope analysis, land use, and soil group. The map below combines all factors into a comprehensive map showing which areas of SSLC are most at risk of poor storm water drainage, and thus would benefit most from the planting of trees. Darker shades indicate higher intervention needs, highlighting areas where increasing the urban forest would have the most significant impact. 

Based on our observations, we conclude that the area of SSLC north of Mill Creek, between I-15 and State Street would benefit most from an increase in the urban forest. By including these factors, we aim to create better draining and more resilient neighborhoods for South Salt Lake residents.
