--- Created: 2026/06/28 08:07 --- ## 1. Effectiveness of Soil Perforation to Reduce Waterlogging ## 2. Micro-climate Impact of Large Scale Household Level Rooftop Gardening ### Scopes - [ ] Temperature impact on immediate below floor - [ ] Urban runoff reduction through rainfall watering instead of manual - [ ] 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.
