Overview of Garissa's Geographical Location and Susceptibility to Flooding

Geographical Location:

- Garissa is situated in the eastern part of Kenya, approximately 350 kilometers northeast of Nairobi.

- It lies along the Tana River, which is the longest river in Kenya, making it vulnerable to riverine flooding.

- The region experiences a semi-arid climate, characterized by erratic rainfall patterns with intense seasonal variations.

#### Susceptibility to Flooding:

- Garissa faces the risk of flooding due to multiple factors, including its low-lying topography, proximity to the Tana River, and inadequate drainage infrastructure.

- The semi-arid climate exacerbates the impact of floods as the soil is often unable to absorb heavy rainfall, leading to rapid runoff and flash floods.

- Urbanization and land-use changes have also contributed to increased surface runoff and decreased infiltration, further elevating the flood risk.

### Historical Floods and Their Impact on the Region

#### Past Flood Events:

- Garissa has a history of recurrent flooding, with notable events occurring in recent decades.

- Major floods have been recorded during periods of exceptionally heavy rainfall, leading to widespread devastation in the region.

- Floods in Garissa have affected both urban and rural areas, causing damage to infrastructure, homes, agricultural land, and livelihoods.

#### Impact on Communities:

- Floods have had a profound impact on the lives of people in Garissa, resulting in loss of lives, displacement of populations, and destruction of property.

- Vulnerable communities, including those living in informal settlements and along riverbanks, are particularly affected by flooding, facing heightened risks to their safety and well-being.

- The economic repercussions of floods are significant, disrupting agricultural activities, trade routes, and local businesses, and impeding the region's socio-economic development.

### Climate Change and Its Influence on Flood Occurrences

#### Changing Climate Patterns:

- Climate change has intensified the frequency and severity of extreme weather events, including heavy rainfall and flooding, in Garissa and across Kenya.

- Increasing global temperatures have led to shifts in rainfall patterns, with some areas experiencing more intense precipitation events while others face prolonged dry spells.

- Variability in weather patterns poses challenges for flood prediction, early warning systems, and adaptive strategies to mitigate the impact of floods.

#### Adaptation and Resilience:

- Addressing the impact of climate change on flood occurrences requires proactive measures to enhance community resilience and adaptive capacity.

- Integrated approaches to water resource management, land-use planning, and infrastructure development are essential for building resilience to floods and other climate-related hazards.

- Sustainable development practices, including ecosystem restoration and natural resource conservation, can help mitigate the effects of climate change and reduce vulnerability to flooding in Garissa and similar regions.

Understanding Garissa's geographical context, historical flood events, and the influence of climate change is crucial for developing effective strategies for flood preparedness, mitigation, and response in the region.

### II. Understanding Floods

#### Definition and Types of Floods

1. Flash Floods:

- Flash floods are sudden and intense floods characterized by a rapid rise in water levels, typically occurring within a short period, often as a result of heavy rainfall or the rapid melting of snow or ice.

- These floods can occur with little or no warning, posing significant risks to life, property, and infrastructure.

2. Riverine Floods:

- Riverine floods occur when rivers or streams overflow their banks due to prolonged rainfall, snowmelt, or a combination of factors.

- In Garissa, riverine floods are a common occurrence, particularly during the rainy season, as the Tana River and its tributaries swell, inundating nearby areas.

3. Urban Floods:

- Urban floods result from inadequate drainage systems, impermeable surfaces, and rapid urbanization, leading to surface runoff and localized flooding in urban areas.

- Factors such as poor urban planning, encroachment on floodplains, and insufficient stormwater management exacerbate the risk of urban flooding in Garissa.

#### Causes of Floods in Garissa

1. Heavy Rainfall:

- Garissa experiences seasonal rainfall, with the long rains occurring from March to May and the short rains from October to December.

- Intense rainfall events, especially during the rainy seasons, can overwhelm drainage systems and trigger flash floods and riverine floods in the region.

2. Poor Drainage Infrastructure:

- Inadequate drainage systems, including blocked or poorly maintained drains, culverts, and canals, contribute to the accumulation of surface water and increase the risk of flooding in urban and rural areas.

3. Deforestation and Land Degradation:

- Deforestation and land degradation disrupt natural hydrological processes, reducing the soil's ability to absorb water and increasing surface runoff.

- Rampant deforestation along riverbanks and in upstream areas exacerbates soil erosion, sedimentation, and the likelihood of flash floods and riverine floods downstream.

4. Urbanization and Land-Use Changes:

- Rapid urbanization and expansion of settlements in Garissa lead to the conversion of natural floodplains and wetlands into residential and commercial areas.

- Encroachment on flood-prone areas reduces natural buffer zones and increases the vulnerability of communities to urban floods.

#### Flood Risk Assessment and Mapping in Garissa

1. Data Collection and Analysis:

- Conducting surveys and collecting data on historical flood events, rainfall patterns, topography, land use, and infrastructure in Garissa.

- Analyzing spatial data using geographic information systems (GIS) to identify areas prone to flooding and assess the associated risks.

2. Vulnerability Assessment:

- Assessing the vulnerability of communities, critical infrastructure, and key assets to flood hazards, considering socio-economic factors, population density, and exposure levels.

3. Flood Hazard Mapping:

- Developing flood hazard maps to visualize the extent and severity of flooding in Garissa, delineating floodplains, high-risk zones, and areas of concern.

- Incorporating data from hydrological models, remote sensing, and community input to improve the accuracy and reliability of flood hazard maps.

4. Risk Communication and Management:

- Communicating flood risk information to stakeholders, including government agencies, local authorities, communities, and the private sector, to facilitate informed decision-making and risk reduction measures.

- Integrating flood risk mapping into urban planning, disaster preparedness, and emergency response strategies to enhance resilience and minimize the impact of floods in Garissa.
