Planning of Rainwater Infiltration Wells Based on Field Permeability Test Results at Sunan Giri University, Surabaya

Abstrak

High rainfall intensity combined with low water absorption can lead to flooding and even disasters like urban floods. Sunan Giri University Surabaya (UNSURI) is one of the educational facilities in Surabaya city, specifically located on Brigjen Katamso Street, Waru District, Sidoarjo. One way to reduce or prevent flooding is by planning the construction of rainwater infiltration wells on the ground surface designed to capture rainwater, allowing it to seep into the soil. The system used in this planning is a field permeability test, where permeability is the soil's ability to allow water to pass through, influenced by its porosity and the stability of its aggregates. The objective of this research is to understand how to conduct a permeability test in the field and determine the number of infiltration wells to be constructed within Sunan Giri University Surabaya. The research results provided data for planning the construction of approximately two infiltration well locations.
