1. Effectiveness of Soil Perforation to Reduce Waterlogging

2. Micro-climate Impact of Large Scale Household Level Rooftop Gardening

Scopes

Urban runoff reduction through calculated watering based on crop demand
Water source analysis; feasibility of greywater reuse

Title 1: Optimizing Rooftop Garden Irrigation for Stormwater Retention in Dhaka

Synopsis

Determine how much stormwater retention capacity can be recovered if irrigation is strictly managed based on real-time crop water demand rather than manual guesswork.

Methodology

Historical hourly and daily rainfall, temperature, and relative humidity data from BMD
Determine Daily Crop Water Requirement for typical Dhaka rooftop crops
Simulate: A. keeping garden near saturation capacity; B. leave a buffer for rainfall
Convert a percentage of building roofs into "Green Roof"
Quantify the difference in peak runoff reduction and hydrograph delay during heavy rainfall events

3. Magnitude of Soil Erosion due to Overland Flow

Scopes

Quantify and map distribution of soil erosion rates within selected area
Evaluate soil losses before and after monsoon seasons
Identify critical regions or soil erosion hotspots

4. Planform of Meghna River

5. Evaluating Drainage Bottlenecks and Waterlogging in Mohammadpur, Dhaka
