Direct Attack

The campaign in the Punjab saw Alexander, supported by his Indian ally Taxiles, attack Porus, who lived beyond the Hydaspes River. The battle, at the beginning of the monsoon season, involved a division of the Macedonian forces. One part faced Porus at the river crossing, where the current and the elephants in the Indian army made a direct attack virtually impossible. Alexander took a portion of his army and marched upstream. Once across the river, he drew Porus away from his defensive position and defeated the Indian ruler in a battle fought primarily by cavalry, although the Macedonian pikemen inflicted injuries on the elephants, which became a danger to their own troops. After the Hydaspes victory, Alexander advanced to the Hyphasis (Beas), where the army refused to cross in order to march to the Ganges. The whole episode was contrived, since Alexander clearly had no intention of going farther east. His failure to reach the eastern end of the world was thus attributed to the timidity and war-weariness of his soldiers. During the descent of the Indus river system, Alexander received a near-fatal wound at the hands of the Mallians. Once he recovered, Alexander conducted a series of bloody massacres as he sailed to the mouth of the Indus and accomplished his goal of sailing out into the ocean. Although the Indian campaign was by far the bloodiest of the expedition, there was little long-term gain from the conquest.

Despite receiving accolades for being the example of cooperation, India and Pakistan's peaceful management of their Indus River system remains largely unexamined. Scholars that do consider this case classify it as passive cooperation. To support their classification, they point to the Indus Waters Treaty's allocation of the river system between India and Pakistan and suggest that it severed the interdependent relationship and need to cooperate. Consequently, this paper seeks to demonstrate that India and Pakistan remain interdependent in managing their Indus River system and for over 40 years, they have sustained active cooperation. To account for the maintenance of this cooperation the paper argues that it is necessary to consider the design of the Permanent Indus Commission, an institution established to manage the Indus River. The ability of Indian and Pakistani commissioners to communicate directly and hold regular meetings permitted them to perform the necessary standard and operating procedures for the functioning of the institution. The commission's ability to monitor development of the river system has enabled it to ease member states’ fear of cheating and confirm the accuracy of all exchanged data. Finally, its conflict resolution mechanisms have permitted it to negotiate settlements to disputes as they arise.

The Face

The endemic freshwater dolphins in the Indus River system of Pakistan, Platanista minor, have been considered endangered since the early 1970s. Measures taken to protect them from deliberate capture seem to have stopped a rapid decline, and combined counts in Sindh and Punjab provinces since the early 1980s suggest a total population of at least a few hundred animals. Severe problems remain, however. In addition to the risks inherent to any species with an effective population size in the low hundreds (at most), these dolphins are subject to long-term threats associated with living in an artificially controlled waterway used intensively by humans. Irrigation barrages partition the aggregate population into discrete subpopulations for much of the year. Dolphins that ‘escape’ during the flood season into irrigation canals or into reaches downstream of barrages where winter water levels are low have little chance of survival. A few dolphins probably die each year after being caught in fishing nets. Pollution by untreated urban sewage, agricultural runoff and industrial effluent threatens the health of the entire Indus system. The future of this dolphin species depends on Pakistan's commitment to protecting biological diversity in the face of escalating human demands on dwindling resources.

Runoff Model

The rivers originating from middle and greater Himalayas have a significant part of their catchments under permanent snow cover and glaciers. Modeling runoff becomes difficult with almost no data from these parts. Even in the seasonal snow covered zones, the network is generally inadequate. However precipitation characteristics show repetitiveness and snowline movement elevation wise by and large occurs the same pattern each year. The snowline movement is distinct on a monthly basis and the location of permanent snowline is also more or less constant at about 4,500 m. A simple monthly snowmelt runoff model with relatively few parameters is proposed to take advantage of above mentioned characteristics, using the degree day method. The model uses monthly rain, snow (snow water equivalent), mean air temperature and snowline elevation as primary inputs. Model conceptualisation has been made in view of the data constraints. All parameters are estimated through few trial simulations, except the storage coefficient, which is optimised using Rosenbrock technique. The model was applied on two sub-catchments of Chenab basin (of Indus river system) to evaluate the model capability. The results are encouraging. There is further scope for model improvement, generalisation and for application to other catchments in the Western Himalayas.

Glacial Advance

AbstractIn the north-western Himalaya, the distribution of modem glaciers and snowlines in the Ladakh and Zanskar Ranges adjacent to the Indus River valley suggests comparable climatic conditions prevail in the two ranges. Similarly, the positions of terminal moraines and reconstructed equilibrium-line altitudes (ELAs) indicate equivalent magnitudes of Neoglacial and Late Glacial advances in both ranges. However, the terminal positions and reconstructed ELAs from the late Pleistocene maximum advances are at least 400 m lower in the Ladakh Range than in the nearby Zanskar Range. These differences do not appear to reflect either climatic or tectonic controls. Rather, they are caused by an unusual bedrock configuration in the Zanskar Range, where vertical strata of indurated sandstones and conglomerates, and narrow steep-walled canyons cut through them, created a bulwark that effectively precluded significant down-valley advance. Without recognition of this physical impedance to glacial advance, uncritical reconstructions would greatly overestimate the altitude of the ELA in the Zanskar Range.
