The River as Relationship: Water, Land, and Human Life
The word “river” originates from the Latin word “ripa”, meaning bank or shore. This origin reveals something important: early definitions of rivers were not centered on the water alone, but on the land the water shapes. A river was understood through its banks—what it carves, creates, separates, connects, and sustains. In this sense, a river is not merely flowing water; it is a relationship between water and land. A true definition of a river, therefore, is a natural, flowing system defined by its interaction with terrain, bounded by banks that are not fixed but dynamic, constantly reshaped by movement, sediment, and time.
Rivers originate from precipitation—rainfall and snowfall. Part of this water flows directly as runoff into streams and rivers; some evaporates back into the atmosphere; and some infiltrates the soil providing moisture to the soil, groundwater recharge and aquifer systems. A portion of this infiltrated water slowly seeps back into rivers as baseflow, sustaining their flow long after the rain has stopped regulating seasonal flow variability.
Driven by gravity, rivers move from higher elevations to lower along the hydraulic gradient, carving their own paths through erosion, transport and deposition as they go. Along the way, they grow, evolve, divide, merge, and take on different identities and purposes through hydrological regimes and geomorphic characteristics. Rivers sustain life while occasionally claiming it; they sculpt valleys, transport sediments, reshape terrains, and link ecosystems. In their dynamic course, rivers serve multiple roles—nourishing, eroding, and connecting. They flow relentlessly-continuously advancing toward the ocean.
Rivers are vital for the formation of landscapes, the sustenance of ecosystems, and the survival of all life forms, including humans. Many of the world’s earliest civilizations arose in the fertile floodplains of major rivers—the Nile nourished the Egyptians, the Indus (Sindhu) supported the Harappans, and so on. As human societies developed, rivers became crucial sources of irrigation, trade routes, and pathways for the movement of people and ideas. They shaped settlements into towns, powered industries, and continue to remain essential today. Looking at a world map, it is clear that many major cities are situated on rivers. In Nepal, numerous cities and towns are located beside rivers, including Kathmandu on the Bagmati, Jumla on the Teela, Taulihwa on the Banganga, Dhangadhi on the Mohana, Mahendranagar on the Mahakali, Butwal on the Tinau, Twelve on the Lalbakaia, Tulsipur on the Patukhola, Gamgadhi on the Mugu Karnali, Biratnagar on the Bakraha, Jomsom on the Kali Gandaki, Virendra Nagar on the Nikaskhola, Dhanusha on the Hardinath, Pokhara on the Seti, Besisahar on the Marsyangdi, and Dunai on the Thulo Veri. These examples highlight how rivers have shaped human settlements and remain central to livelihoods, culture, and economic development.
River are source of essential freshwater, vital to the culture, ecological equilibrium and almost every aspects of life - at least, we say so. Many urban rivers have lost the characeristics of river, I boldly claim they are not rivers. Other rivers are diverted and dried up for electricity(Hydro), for energy, for human comfort. I am not here to state whether this is wrong or right. Its upto you, the reader, to decide.
In Nepal, people revere the rivers (water body) as holy, at least we think so, but our action tell another story. Philosophically, the river symbolizes purification and the cycle of life/death. Today this sanctity clashes with reality.
