## 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. Evaluating Drainage Bottlenecks and Waterlogging in Mohammadpur, Dhaka
